New treatment option for Irregular Astigmatism
Official title Improving Visual Quality in Patients With Irregular Corneas Using Asymmetrical Toric Intraocular Lenses
ClinicalTrials.gov ID: NCT07294716
What this study is testing
- What it's testing
- Cataract surgery in patients with irregular corneas presents unique challenges, primarily due to the high variability in keratometry and corneal tomography measurements, which complicates accurate intraocular lens (IOL) calculations. In these patients, therapeutic options are currently limited to either non-toric IOLs and rigid contact lenses postoperatively or conventional toric IOLs for the reduction of total astigmatism within cataract surgery.
